TORONTO staircase riser bar kit

Designed to match your DOLLE TORONTO staircase. You can use riser bars to improve safety by mounting them under the treads as a barrier to close the gap. This is an important safety feature and a requirement for UK Building Regulations if the staircase is to be used as a primary staircase. For a spiral staircase to comply it must not have a gap over 100mm, installing the riser bar kit will ensure compliance.

The package includes 17 riser bars made of galvanised steel and you will get all the fixings you need for an easy install.
